Extended PCM Interface Controller – Small (EPIC -S)

General Description

Information from subscriber lines needs to be transferred to

time-slots on system internal PCM communication highways.

The EPIC-S concentrates the circuitry necessary to do this

interfacing for a large number of transmission lines on a

single IC. Therefore, it is not necessary to repeat this PCM

interface circuitry for every line. Applications of the EPIC-S

include communications multiplexers, concentrators, central

switches, PBXs, as well as peripheral ISDN and analog line

cards.

Features

• PCM interface controller for up to 16 ISDN or 32 analog

• Time-slot assignment freely programmable for all

• Non-blocking switch for 64 channels

• Switching of 16-, 32-, 64-kbit/s channels (128 kbit/s via

two consecutive 64-kbit/s channels)
